Ok everybody, I'm looking for a fic that was at a Single Spark and fanfic.net (don't know if it's still there). All I remember is the lemon part (I wonder why is that? ) where Kagome ends up restoring Sesshomaru's arm by channeling her powers through Mokomoko. They're in a cave, and the first person to find them afterwards is Sango, who doesn't recognize Sessho at first because he has his back to her and obviously both arms.
